GIS is considered an important technique as well as a prerequisite for cost effective mineral exploration and determination of high potential areas. The purpose of this research is to determine high potential iron zones for detailed exploration using index overlay GIS method. Index Overlay was used to combine the geology, topography (scale: 1:1,000), lineaments, remote sensing (ASTER and ETM+) ...

This paper presents an overview of the GIS and remote sensing applications in natural resources management in Bangladesh and the information were taken from secondary sources. The first national Agro-Ecological Zone (AEZ) database was prepared in the period from 1980 to 1987. The database contains information on the country's land resources including physiography, soils, climate, hydrology, cro...

Managing complex tropical forest requires up to date technology in ensuring sustainable resources utilisation. Much of the current forest management practices can be improved through the use of current technologies including remote sensing, GIS (Geographic Information System) and GPS (Global Positioning System) which may enhance any decision making process. This paper highlighted the use of cur...

Following a comprehensive literature review, this paper looks at analysis of geohazard using remote sensing information. This paper compares the basic types and methods of change detection, explores the basic principle of common methods and makes an respective analysis of the characteristics and shortcomings of the commonly used methods in the application of geohazard. Using the earthquake in J...
